[2.0] filter spam domains from referers list

Not sure if this is possible with the spam.module, but I'd love to see the module somehow block/hide referer log entries that contain spammer URLs... or at least have it's own view of the list -- it's way too hard to scan where links are coming in from when 27 items out of every page of 30 is a *casino*, *mortgage*, or *viagra* domain. :)
